ABSTRACT:
An improved Solar Pond Apparatus is described which comprises a solar pond means having a substantially flat, extended surface with upwardly directed sides thereof to retain the liquid while the liquid is exposed to the sun absorbing solar radiation and a flooding valve means connected to the solar pond means and moveable between an open position and a closed position to provide the liquid from the source and flood the liquid upon the substantially flat, extended surface of the solar pond means. Means are provided to control the depth of the solar absorbtive liquid and flooding valve control means are connected to the flooding valve means and to the means to control the depth of the solar absorbtive liquid which activates the flooding valve means to the open position when the means to control the depth of the solar absorbtive liquid determines the liquid in the solar pond means and which activates the flooding valve means to the closed position when the means to control the depth of the solar absorbtive liquid determines the second level of liquid in the solar pond means. First liquid conduit means are connected to the source of the flooding valve means and drainage valve means are connected to the solar pond means and are moveable between an open position and a closed position to drain the liquid from the solar pond means. A first sensor means is attached to the solar pond means and arranged to sense a predetermined temperature and drainage valve control means are connected to the drainage valve and to the first sensor means which actives the drainage valve means to the open position when the first sensor means senses the predetermined temperature. Storage means are connected on one end to the drainage valve means to receive the liquid at the predetermined temperature therefrom, and on the other end to an outlet means. Second liquid conduit means connect the drainage valve means to the storage means.
